Be unknown that 1, Rio mould. NoR'ioN, a Gilli 611;.OfftllQIlnltGd States, residing at ashingtoinf District ofColinnbia, have in; vented i certain new and useful IIltpl'OYQn ments in-Adjusters for Flexible Pendants of which the following is a si ieciiication,reierence beinghad to the accompanying draws 1ng.- a p 7 i 1 y a This inventionrelates ito fixture supports andqmore particularly toa means for adjust: ably positioning a flexible i pendant; fixlaire in; agvortical plane.

One of theniany objects oi this invention is to provide a device of thenaturedescribed wh iclmnay be roa dily installed on a pendant fixture without;dctaching any of the parts of the latter: a l i l Another,objcctiis to have thedeviceso arranged thatwno severe orrelatively inj unions stresses will belput upon parts of the pendant or its insulation. i

A further object is to nrrange the ineans for balancing the fixture proper 0 that its weight may be readily adjusted and after thesaino is in po ()the' objects are, to arraiige the parts Oil I thedevice so that they maybe quickly do tached or fastened together WllliOl'lt the use of tools; to eliminate extra cords for supporting the balancing weight; to arrange the support for the weight whereby the latter will be kept out of contact with the pendant proper, and to have the device as simple and compact as possible and consistent with the work to be done; other objects of this invention will be apparent as it is more tully set forth.

In most devices for adjustably supporting pendants a separate support has to be provided for the adjuster whether a spring or about two inches of the latter.

weight is used, and in some cases several are used, and require a large amount of flexible cord or tubing in order to make their use with the device convenient. This invention avoids these disadvantages in that it is directly attached to the flexible pendant cord or tubing and requires or uses up At the same time no excessive stresses are placed on the cord or tubing at any time, and the device can be installed or removed in a relatively very short time.

In the accompanying drawings which show a modification of this invention, Figure 1 shows an embodiment of this invention Specification of Letterslatent.

At a suitable point of the cord, aoclanip isattached, the latter being pretel ably ot the form shown in the. drawings. a i

5 and 6 are respectively the legs of the clamp and are provided i'wiitlr Vy-sluiped grooves 'l therein, for the cord to lie} and be clamped on. Theleg 6 hingcdly connected ed 1: sition by means oi a threaded bolt T8;

which extends through the leg 6 and threads rub) the leg o, a suitable head i) bein pro-i vided on it, so that it can be actuated by g hand;- A pairot legs 1 and all, ext-e; aw iii'rom the clamp properin anopposite direction to those already mentioned serve as holders for a journal shaft 12 fora pulley 13 which :lfreely rotates thereon. The end 14 of the shaft 12 threads into the leglO and its head 15 is preferably mad) as shown.

The balancing member oi the device con sists Oil a quasi-spherical body 16 of rela' tively heavy material, provided with a; deep curved groove 17 adapted to permit a pullo; 18 to be disposed therein. A removable pin 19 disposed in holes 20 in the body 16 serves to help the pulley in place. The principle oi this pin is similar to that of the parts 12 and 8. At the lowest portion of the groove 17 a hole leads to a space or hollow 21 provided in the body. This hollow for the reception oi shot or other loading inediinn, so that the weight 01'' the fixture can be accurately counterbalaneed.

It will. be noted that the groove 17 is suliiciently deep to permit the shot to be easily placed in the weight even. when it:

is positioned with the cord in place. In order to permit the cord to be extended as far as possible the body is cut away atone side 22 oi the groove 17 in such a way as to permit the pulleys to come into close contact if desired. This last position of the pulleys gives them a slight braking acapplied to a, flexible cord pcndant fintnre.

tion which permits the lamp to be handled and raised a slight amount for general purposes, without permitting the body to descend.

It is unnecessary to detail the position of the lamp cord in the device as the drawings indicate the same and it can be readily appreciated from the foregoing description that the pulleys can be quickly removed and replaced and the clamp fastened on at hwithout any tools or removal of or interference with any parts of the fixture itself.

\Vhile but one form of the device is shown it is understood that this application for 5 patent is not limited to that particular form be readily slidable thereon and the other end portion is adapted toreceive, and provlded with, a pulley, means for retalning the pulley in place in the portion, said pulley being grooved for the cord, and a balancing member having a pulley recessed (loplel of this patent may be obtained for thereinand means for retaining the pulley in place adapted to be quickly removed and replaced, said pulley being grooved to ride on said cord, said balancing member being arranged to counterbalance the lamp and take up the cord when adjusted.

2. In combination with a flexible cord and pendant fixture, an adjuster comprising an elongated body having its end portions bifurcated, one portion being adapted to clamp and offset the flexible cord and to be slidable thereon, and to cause the body to extend angularly out from said cord, the other of said portions being adapted to retain a pulley, said pulley bein grooved for the flexible cord and disposed away from the cord offset by the first portion, and a balancing member having a pulley completely recessed therein and arranged to ride on said cord and bring it adjacent to the inside of the member whereby it will not be able to jump the cord, and means for retaining the Wheel easily removably in place, said balancing member being arranged to counterbalance the fixtureand talze-up the cord when adjusted and avoid contact with the cord adjacent to the lamp. In testimony whereof I hereunto aifix my signature in the presence of two Witnesses.
